<p>Escapes a string for use in a URI.</p>
<p>Normally all characters that are not "unreserved" (i.e. ASCII alphanumerical
characters plus dash, dot, underscore and tilde) are escaped.
But if you specify characters in <em class="parameter"><code>reserved_chars_allowed</code></em>
 they are not
escaped. This is useful for the "reserved" characters in the URI
specification, since those are allowed unescaped in some portions of
a URI.</p>
